Abstract

THE MAJOR PROBLEMS IN COCOA PRODUCTIVITY ARE THE ATTACK OF VARIOUS DISEASES, THE MAIN ONE BEING THE WITCHES�€™ BROOM, WHICH IS CAUSED BY THE FUNGUS MONILIOPHTHORA PERNICIOSA. THIS WORK AIMS TO EVALUATE THE SUPPRESSION OF WITCHES' BROOM DISEASE AND THE EVALUATION OF GROWTH PROMOTION IN COCOA SEEDLINGS WITH THE USE OF BIOAGENTS. THE EXPERIMENT WAS CONDUCTED IN A COMPLETELY RANDOMIZED BLOCK DESIGN, UNDER SCREEN CONDITIONS, WITH THE FOLLOWING TREATMENTS: T1- CONTROL; T2- TRICHODERMIL�® (TRICHODERMA HARZIANUM); T3- BACILLUS SP.; T4- BURKHOLDERIA PYRROCINIA. TWO TYPES OF APPLICATIONS WERE PERFORMED, ONE LEAF AND THE OTHER IRRIGATION, WHICH OCCURRED SIMULTANEOUSLY, TO ASSESS THE SEVERITY OF THE DISEASE, THE TREATMENTS WERE APPLIED AT 7, 14, 82 AND 90 DAYS AFTER PLANTING. IN THE RESULTS OBTAINED, ALL THE BIOAGENTS TESTED WERE CAPABLE OF THE DISEASE, IN ADDITION TO HAVING POTENTIAL IN PROMOTING PLANT GROWTH.
